FREETOWN — Selectmen filled a vacancy on the Finance Committee and accepted the resignation of a longtime Zoning Board of Appeals member at their meeting Tuesday.

In a letter read by Selectman and Personnel Board Chairman Paul Sadeck, Appeals Board member Gary Guinen said he is resigning effective May 31.

“I have no regrets, but I do feel that it’s time to leave,” Sadeck said, reading from the letter.

Sadeck praised Guinen’s decades of service to the town.

“He’s served us for 20 years and he’s been a great member of the Board of Appeals,” he said.

The board voted unanimously to accept the resignation; no potential replacements for Guinen were discussed.

In other business, selectmen voted unanimously to appoint Conservation Commission member Christopher Mather to fill a vacancy on the Finance Committee.

The seat had been vacant for two years and, commenting after the meeting, Finance Committee Chairman Bradford Paiva said the committee had been trying to fill the seat ever since it became open.

He expressed confidence that Mather would be a welcome addition to the committee.

“We’ve got a gentleman with a lot of good qualifications,” he said.

Prior to his appointment, Mather sat in on a joint session between the selectmen and the Finance Committee, who reviewed several town departments’ proposed budgets in advance of the June 2 Town Meeting.

Selectmen Chairwoman Lisa Pacheco expressed concern about the amount of money several departments had budgeted for leasing vehicles.

She said that leases are long-term financial commitments that could not be easily cut if a budget has to be reduced in a later year, forcing the department to make cuts in other areas.

“You’re going to be cutting people,” she said.

Selectmen and the Finance Committee will resume budget reviews at a meeting next week.
